Question

1. assume red blood cells are about 10% solute and 90% water. label each beaker below as hypertonic, hypotonic, or isotonic, compared to the cell. will each cell shrivel, blow up, or remain unchanged? draw arrows to show the movement of water in or out of the cells

Explanation:

Step1: Define solution - types

Hypertonic has higher solute concentration than cell, hypotonic has lower, isotonic has equal.

Step2: Analyze first beaker

10% solute and 90% water in beaker, same as cell. So it's isotonic. No net water movement, cell remains unchanged.

Step3: Analyze second beaker

50% solute and 50% water in beaker. Higher solute concentration than cell (10% solute). It's hypertonic. Water moves out of cell, cell shrivels.

Step4: Analyze third beaker

0% solute and 100% water in beaker. Lower solute concentration than cell. It's hypotonic. Water moves into cell, cell blows up.

Answer:

First beaker: Isotonic, cell remains unchanged.
Second beaker: Hypertonic, cell shrivels.
Third beaker: Hypotonic, cell blows up.
